问题描述
我正在尝试升级我的项目 L5.1 -> L5.2.在升级指南中,我不清楚一件事:
I'm trying to upgrade my project L5.1 -> L5.2. In upgrade guide there's one thing which isn't clear for me:
集合、查询构建器和 Eloquent 查询上的 lists
方法builder 对象已重命名为 pluck
.方法签名保持不变.
The
lists
method on the Collection, query builder and Eloquent query builder objects has been renamed topluck
. The method signature remains the same.
没关系,将重构从 lists()
重命名为 pluck()
不是问题.但是 L5.0 和 L5.1 中有用的 pluck()
方法呢?
That's ok, rename refactoting from lists()
to pluck()
isn't a problem. But what with useful pluck()
method which was in L5.0 and L5.1?
来自 5.0 文档:
从一行中检索单列
$name = DB::table('users')->where('name', 'John')->pluck('name');
L5.2 中旧的 pluck()
方法的替代方法是什么?
What is the alternative for old pluck()
method in L5.2?
更新:
示例:
var_dump(DB::table('users')->where('id', 1)->pluck('id'));
L5.1:
// int(1)
L5.2:
// array(1) { [0]=> int(1) }
推荐答案
pluck()
目前的替代方案是 value()
.
The current alternative for pluck()
is value()
.
